The current version of the program uses an "in-core" equation solver and does not renumber the nodes for minimum storage, making it suitable only for relatively small structures. The structure is modeled as a 3D assemblage of nonlinear elements connected at nodes. The program documentation allows for both conventional nodes and "compound" nodes.
